pH is just an indicator. I don't believe the CO2 injection pH-drop actually makes any difference to any plants or fish. In other words, if you had hard water to start with, the plants and fish will still see hard water. It is the hardness/TDS that matters, not the pH. So controlling the pH with CO2 is pointless; it is only of use as a nutrient. PS 99% of plants like fairly hard water :p
